How to fetch the Alias column values based on different column values?

Question

Hello Gurus,
I have a table with the following struture -
"drop table T;
create table T(Name, Symbol, Amount,dep) as select
'Anderia', 'AA', 1050000,'HR' from dual union all select
'Michael', 'ML',150000,'Sales' from DUAL union all select
'Bill', 'BL', 1050000,'Finance' from dual union all select
'Nancy', 'NY', 4000,'HR' from DUAL union all select
'Anderia', 'AA',3000,'HR' from dual union all select
'Michael', 'ML',1050000,'Sales' from DUAL union all select
'Bill', 'BL', 1200000,'Finance' from DUAL union all select
'Anderia', 'AA', 1200000,'HR' from DUAL union all select
'Vish', 'VH', 1200000,'Marketing' from DUAL;"Ans try to find out the values of the column like
Name,symbol,dep,Amount,%Total,$Cumm Total, Rank but some additional columns like -
HR Amount, %HRTotal,$HR Cumm Total,
Finance Amount, %FinanceTotal,$Finance Cumm Total
Sales Amount, %SalesTotal,$Sales Cumm Total,
Marketing Amount, %MarketingTotal,$Marketing Cumm Total
then i am using the following query to fetch the Name,symbol,dep,Amount,%Total,$Cumm Total, Rank columns -
select name
     , decode(grouping(symbol), 0, symbol, 'Total') symbol
     , dep
     , sum(amount) amount
     , sum(per_total) "% Total"
     , decode(grouping(symbol), 0, max(Cum_per_total), null) "% Cumm Total"
     , decode(grouping(symbol), 0, max(rank), null) rank
  from (
          select name
               , symbol
            , dep
               , amount
               , per_total
               , sum(per_total) over(order by rk) cum_per_total
               , rank
               , rk
            from (    
                    select name
                         , symbol
                , dep
                         , sum(amount) amount
                         , round((sum(amount)/max(total_amount)) * 100,2) per_total
                         , dense_rank () over (order by sum(amount) desc) as rank
                         , row_number() over(order by sum(amount) desc) as rk
                      from (
                             select name
                                  , symbol
                                  , amount
                      , dep
                                  , sum(amount) over() total_amount
                                  , sum(amount) over ()
                               from t
                     group
                        by name, symbol, dep
  group        
     by grouping sets((name, symbol, dep), ())

Hello Frank Kulash/Łukasz Mastaler,
Thanks for your time and effort.
I am using the Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production
I am looking forward to have some additional columns (column alias) along with the the returned by the mentioned query - which are named as -
1- HR Amount
2- %HRTotal
3- %HR Cumm Total
4- Finance Amount
5- %FinanceTotal
6- %Finance Cumm Total
7- Sales Amount
8- %SalesTotal
9- %Sales Cumm Total
10 -Marketing Amount
11- %MarketingTotal
12- %Marketing Cumm Total
based on the logic like -
HR Amount = sum of amount case dep ='HR'
%HR Total = % of amount case dep ='HR'
%HR Cumm Total (cumulative % based on the cumulative total of %HR Total) = Cumm % of amount case dep ='HR'
similarly rest of the column........
Now how do i use case with a logic so that it returns me the columns as i want them ...using the above mentioned query .......
Kindly help me .....thanks in advance for all of your time
